testsuite not working, please change "assert(isequal(pidigit(N,n)-y_correct

Thanks, I have made the change

Still missing a ")" in your assert statement

Thanks, I have add ')'

In Solution 1301292 I am finding the same thing as Yona reported (see comment below). "Digits" should mean all digits, including the leading 3. That is the definition required to pass Test 1. But to pass Test 2 and Test 5, it is required to ignore the leading 3. Or else some people have misread the problem statement, which says that the number of digits to inspect is not N, but rather N–1. (Because we're trying to predict the N'th digit.) I count only 15 occurrences of "6" in the first 200 digits, when the leading "3" is included (as it should be).

I can not find a solution without using the symbolic math toolbox ;(

David, Maurício, Yona and mhartma3 check your solutions. They should pass all the test suit now.

Thanks, Mehmet OZC. I suppose that numerically my Solution 1301292 should now pass, but it seems it is failing the new assertion that uses regex to parse the M-file. I guess it is looking for hard-coded solutions that might characteristically contain any of the numbers [101,201,202,203,1001], which are important parameters in your Test Suite. However, inspection of pi reveals that the sequence "101" appears at the 852nd decimal place, "201" appears at the 244th decimal place, etc. So the new assertion might be creating unexpected side-effects.
